Social Responsibility Driven Financial Intermediation

Ahmad Mohamed Ali Al-Madani and Royal Professor Ungku Aziz, alongside many other scholars, entrepreneurs, policymakers, bankers and institution-builders. Their collective contribution extended far beyond establishing banks. They created markets, regulatory frameworks, standards, intellectual traditions and human capital that enabled Islamic finance to evolve into a global industry. The pioneers built a bridge. Our generation must now decide where that bridge should lead. The achievement of the first fifty years was to prove that Islamic finance could exist, grow and institutionalise itself. The challenge of the next fifty is to determine how that institutional foundation can serve a wider human purpose.

The Islamic finance industry today represents an extraordinary achievement in institutional development, global reach and financial innovation. From its relatively modest beginnings, it has evolved into a global ecosystem with US$5.78 trillion in Islamic finance assets in 2025, reflecting 21 per cent

while too little attention has been given to genuine risk-sharing, measurable impact and the wider social imagination that the discipline can inspire. Yet the critique should not become a verdict. Islamic finance grew out of post-colonial economies in which the immediate priorities were to mobilise savings, broaden financial inclusion, establish institutional legitimacy and build credibility within financial systems largely designed around conventional models. In that context, gradualism was not only understandable; it was often necessary. The bridge that Islamic finance built between principle and practice served a vital purpose. But a bridge is a means of transition, not the destination. There is a useful precedent outside our tradition. John C Bogle built Vanguard and then spent much of his later life as his own industry’s most loving and persistent critic. His dissatisfaction was not destructive; it was disciplined, constructive and ultimately transformative, helping give the world its first index fund. Islamic finance now needs a similar spirit of insider dissatisfaction. We must ask not only, “Is this transaction permitted?” but also: What does it make possible? Who benefits? Who carries the risk? What remains after the return is distributed?

The Operating Principle: Capital as Amana

These questions need to be considered in the light of the Qur’an: “We offered the Trust to the heavens, the earth and the mountains... yet humanity accepted it” (Qur’an 33:72). The verse highlights the importance of trust as an operating principle. To

A Different Moral Architecture for the Global Economy

The prevailing financial system persists without a soul, reducing many of the world’s economies to debt-ridden architectures. The urgent need today is for a different moral architecture underpinning the financial system. Consider the current state: global public debt stands at a record US$102 trillion, while developing countries paid a record US$921 billion in interest in a single year, and 3.4 billion people now live in countries that spend more on interest payments than on health or education. Global growth is projected at just 2.5 per cent in 2026, the slowest pace since the pandemic. Owners’ capitalism has mutated into managers’ capitalism, where agents are rewarded ahead of the owners they serve; a phenomenon that John C Bogle warned about extensively.

author of The Battle for the Soul of Capitalism (2005), was one of capitalism’s most insightful critics from within.

Bogle argues managers’ self-interest in running a business has outpaced owners’ capitalism, becoming managers’ capitalism. Speculation has crowded out investment: short-term price over long-term value. The more the financial system takes, the less the investor keeps, and the costs decide outcomes. Bogle’s remedy was fiduciary duty, stewardship over salesmanship, and the restoration of trust. These two witnesses remind us that capitalism’s own conscience aligns with Islamic values. These ethical values, which on one hand pervade Islamic teachings, are on the other hand needed to kindle the conscience of conventional financial systems.

The Role of the State: Referee, Umpire and Partner

Markets supply the energy of an economy, but the state supplies the rules of the game and the confidence to play it. The role of the state must be understood in three dimensions: referee, umpire and partner. As referee, the state sets and enforces just rules, drawing on Smith’s second duty of the state: “an exact administration of justice”. As umpire, it remains impartial between all players, protecting the weaker party and adjudicating without fear or favour, with standards applied consistently to state and private actors alike. Our hisba tradition teaches that market oversight is a public trust. As allocator and partner, the

third shift, from debt bias to risk-sharing, emphasises patient investment, entrepreneurship, data-enabled mudaraba and musharaka, employee ownership and partnerships that connect financial returns with real economic activity. The fourth shift, from elite access to democratised wealth, focuses on making investment opportunities accessible to ordinary savers through professionally governed and transparent platforms.

Finally, the shift from compliance to consciousness recognises that rules and technology alone cannot create lasting trust. Ethical character, accountability and genuine concern for others must guide institutional behaviour. Together, these shifts present a vision of Islamic finance that measures success not only through financial performance, but also through its contribution to human dignity and shared prosperity.

Waqf: The Endowment That Built a Civilisation

Waqf represents one of the most enduring examples of Islamic civilisation’s approach to creating lasting social and economic value. For centuries, endowments supported hospitals, universities, libraries and essential public services without relying entirely on state funding (Çizakça, 2000). At its core, waqf is based on the preservation of principal while directing the benefits generated by an asset towards a designated charitable or social purpose. This structure makes it an early example of perpetual capital, in which the original asset remains protected while its

and social potential of waqf through professional management, investment and technology. The model begins with permanent capital, which may come from traditional awqaf, family philanthropy, zakat-related initiatives, corporate giving or impact-first investors. Rather than allowing these resources to remain disconnected from productive activity, the framework proposes investable delivery through professionally governed funds and special-purpose vehicles. These structures can support schools, clinics, housing, food security, clean energy projects and small and medium-sized enterprises. FinTech distribution is another important element, as digital identity, low-cost participation, transparent reporting and secure access can make waqf-related investment and giving more accessible. A focus on verified outcomes ensures that institutions measure the people served, jobs sustained, educational improvements achieved and emissions reduced.

Blended finance is a further element, in which philanthropic capital absorbs justified early risks, commercial investors participate in risk-adjusted opportunities, and governments or development finance institutions provide guarantees or outcome-based payments where appropriate. This arrangement can mobilise larger pools of private capital while preserving the original social purpose of waqf. The central message is that waqf should not replace markets or operate only as charity; instead, it can help design better markets that combine financial sustainability with measurable social benefit.

sits at the centre of any serious vision for the next fifty years.

Takaful is also a powerful instrument for the democratisation of wealth, the fourth of the five shifts described above. Its mutual architecture makes every participant a member rather than merely a customer: the underwriting surplus belongs to the pool, and the pool’s investments belong, in economic substance, to the participants. Family takaful combines protection with disciplined long-term saving, giving ordinary households a professionally managed pathway into investment that was historically reserved for the affluent. Digital distribution and micro-takaful now allow this pathway to reach gig workers, smallholders, micro-entrepreneurs and low-income families at a cost per participant that was unimaginable a generation ago. A takaful industry at scale would therefore do for Islamic finance what pension and insurance capital did for the industrialised economies: create the deepest pools of long-term institutional capital, owned in substance by ordinary people.

The recurring instability of modern finance is not an accident; it is built into the architecture of fractional-reserve banking. Institutions fund long-term, risky and illiquid assets with short-term deposits that are promised back at par on demand. When confidence falters, the model fails, and the state steps in with deposit insurance, liquidity support and bailouts. Gains are privatised in good times and losses are socialised in bad times, precisely the inversion of responsibility that the amana principle rejects.

The Case for Narrow Banking: Intermediation through Asset Management Contracts

There is a distinguished body of thought, from the heart of Western economics, that reaches the same conclusion. Irving Fisher and the Chicago economists of the 1930s proposed full-reserve, or narrow banking in which payment deposits are backed one hundred per cent by safe assets and credit is financed by investors who knowingly bear risk. Researchers at the International Monetary Fund revisited the Chicago Plan with modern modelling tools and found its claimed benefits, dramatically reduced bank runs and business-cycle volatility to be supported. Laurence Kotlikoff has argued for limited purpose banking, in which banks operate as pass-through mutual funds that intermediate risk rather than warehouse it.

funds and platforms in which the institution acts as a fiduciary manager, transparent about performance, remunerated for stewardship, and standing alongside, not above, the investors it serves. This is Bogle’s fiduciary ideal expressed in the grammar of our own contracts. It would give practical effect to the shift from debt bias to risk-sharing at the level of system design rather than product labelling, and it would position Islamic finance not as a variant of a fragile model, but as a leader of a safer one. Regulators have a vital enabling role: recognising investment-account intermediation, requiring transparent pass-through of returns, and ensuring a level tax and prudential playing field for risk-sharing structures.

From Paper Assets to Productive Assets

The transition from paper assets to productive assets reflects a

Artificial Intelligence with Moral and Spiritual Intelligence

Artificial intelligence is the defining general-purpose technology of our era, and finance is among the industries it will reshape most profoundly. Used well, AI can advance every one of the five shifts. It can extend credit assessment to households and small businesses with no formal financial history, bringing the excluded into the system. It can collapse the cost of financial advice and portfolio management, democratising services once reserved for the wealthy. It can strengthen Shari’a governance through intelligent screening, monitoring and research support, and it can sharpen the measurement of social outcomes that a purpose-driven industry requires. But intelligence is not wisdom. An algorithm optimises whatever objective it is given; it does not ask whether the objective is just. Left ungoverned, AI can entrench bias in credit decisions, manipulate behaviour, erode privacy, and accelerate speculation to machine speed.

The question before us is therefore not what artificial intelligence can do, but what we ask of it, and who remains accountable for the answer. Here our tradition speaks with clarity. The human being is khalifa, a trustee, and accountability for every decision, including every automated decision, remains a human amana that cannot be delegated to a machine.

This is what I mean by pairing artificial intelligence with moral and spiritual intelligence. Moral intelligence supplies the

dispute and manipulation. Transparent ledgers allow ownership of underlying assets, and the flow of funds, to be traced from end to end.

The applications across our industry are practical and already visible. In the capital markets, Blockchain can reduce the cost and complexity of sukuk issuance and servicing while proving the existence and performance of underlying assets, a direct answer to the critique of form over substance. Al Hilal Bank executed the first sukuk transaction on Blockchain in 2018, and the world’s first primary sukuk issuance on a public blockchain followed in 2019, a mudaraba micro-sukuk that funded Indonesian micro-entrepreneurs through a genuine profit-sharing structure. That small transaction carried a large message: technology can make authentic risk-sharing viable at micro scale and open the capital markets to issuers and investors who were never able to access them. Beyond the capital markets, distributed ledgers can bring verifiable integrity to zakat, sadaqa and waqf flows, so that every contributor can see that funds reached their intended purpose; to halal supply chains; to trade finance documentation; and to identity and know-your-customer processes that today exclude the undocumented.

A note of humility is warranted. Blockchain strengthens the integrity of processes; it cannot substitute for the integrity of character. A distributed ledger can prove what was done. Only conscience can decide what ought to be done. Used in that spirit, as an instrument of transparency, traceability and trust, this technology can bring greater authenticity to the business

our industry each year from accounting, audit, consulting, law and conventional banking with a rigorous, practical grounding in Islamic finance.

Too much of what is taught remains theoretical, while practitioners need knowledge that is practically implementable on the desk, in the deal and in the boardroom. The industry has under-invested in the structured early-career formation, graduate programmes and internships, through which every great profession renews itself. Experience shows what works. At HSBC Amanah, we invested in a dedicated graduate and management development programme, and the professionals it formed now lead institutions across the global industry; the compounding return on that investment has exceeded any transaction we completed. Conferences and summits, when designed with intent, are not ceremonial gatherings but living platforms where scholarship meets practice and where the next generation meets its role models. Workshops that are case-based and implementable, executive education partnerships with serious universities, and industry publications such as this Report — these itself all form part of the same learning ecosystem.

The proposition is simple. Every Islamic financial institution should commit to a structured graduate trainee intake and internship programme, however modest, and treat learning and development as a first-order strategic investment rather than a discretionary cost. Industry platforms should collaborate to build a recognised foundation curriculum for new entrants and

Each partner contributes different expertise, resources and perspectives, allowing financial capital to support ideas, education, infrastructure and human capability more effectively. The third commitment is to publish the consequences of financial decisions. Institutions should report where money was invested, what risks were shared, who benefited and what changed as a result. Transparent reporting helps stakeholders distinguish genuine impact from broad declarations of purpose. The potential cumulative effect is considerable: if more than 1,500 institutions adopt credible and repeatable solutions, collective action — supported by measurable objectives and transparent reporting — can turn individual institutional commitments into meaningful economic and social transformation.

An Alliance of Goodness

On a broader note, Islamic financial institutions need to build an Alliance of Goodness: a network of cooperation as a foundation for addressing the major challenges facing humanity. Climate change, poverty, food insecurity, healthcare and education are not problems belonging exclusively to one religion, region or civilisation. They affect communities across the world and therefore require shared responsibility and collective action. Islamic finance brings distinctive contributions to this alliance: the traditions of amana, or trust and responsibility, risk-sharing, restraint in the circulation of wealth and service to creation. Together, these principles encourage financial institutions to consider the wider consequences of their decisions and

Economies with a Heart

Economies with a Heart expresses the central vision of a financial system that combines economic productivity with ethical responsibility and human concern. Drawing on Adam Smith’s observation that people possess principles that interest them in the fortune and happiness of others, it challenges the idea that financial success should be measured only through profit, growth or the number of products delivered. Instead, it proposes an economy in which capital understands its purpose and technology expands participation in meaningful ways.

Waqf is presented as an institution capable of regaining its wider civilisational role by supporting long-term social and economic development. Enterprise is recognised as a means of creating dignity through employment, entrepreneurship, innovation and productive opportunity. Profit remains an important and legitimate component of economic activity, but it should serve a broader purpose rather than becoming the sole measure of success. The emphasis is that prosperity based on strong institutions and individuals is connected with the amelioration of vulnerable communities. This perspective encourages financial organisations to consider how their decisions affect people with fewer resources and opportunities. Ultimately, the success of the Islamic finance industry should not be judged simply by the number of products it certifies. Its deeper contribution lies in the lives it improves, the opportunities it creates and the dignity it helps restore. This is the foundation of an economy guided by both efficiency and conscience.

unsustainable because it locks firms into continued virgin-resource extraction, rising waste, and avoidable emissions. In response, the circular economy has matured into a systems framework orientated around eliminating waste and pollution, circulating products and materials at their highest value, and regenerating natural systems. The scholarly literature treats circular business models not as end-of-pipe waste management but as mechanisms that narrow, slow, close, intensify, and dematerialise resource loops.

Running in parallel, sustainability governance has increasingly been organised through the vocabulary of ESG. That development has sharpened board-level attention to sustainability-related risks, metrics, and disclosure, especially since the issuance of IFRS S1 and IFRS S2, which require entities to disclose sustainability, climate-related risks and opportunities that could affect enterprise prospects, cash flows, access to finance, and cost of capital. Yet ESG remains an ambiguous field. Berg et al. (2022) documented substantial disagreement among the major rating providers and traced most of the divergence to measurement differences. The practical hazard is that a firm may improve one rating while neglecting broader sustainability performance and that investors may mistake disclosure sophistication for real-economy transformation.

A second and deeper limitation is that mainstream ESG architecture often privileges financially material information for capital providers. By contrast, the Global Reporting Initiative (2021a) centres an organisation’s significant impacts on the

interests and that solidarity instruments—waqf, sadaqa, and qard—can be mobilised for inclusion and poverty alleviation. In recent scholarship on sustainable takaful and Islamic corporate sustainability, maqasid al-Shari’a has been treated as a framework capable of aligning the protection of life, wealth, intellect, lineage, and religion with contemporary sustainability concerns. These strands now matter in market practice. The global Islamic financial services industry reached US$3.38 trillion in assets in 2023. At the same time, the World Bank and Islamic Development Bank report that Islamic climate finance remains constrained by fragmented governance frameworks, the absence of a common taxonomy, limited human capability, thin project pipelines, and weak data infrastructure, even as Islamic banks, sustainable sukuk, and halal value chains increasingly engage with sustainability strategies. The market, in short, is now large enough to matter but not yet institutionally mature enough to finance transition at scale.

The inquiry also builds on a sustained research programme that has, over the past decade, argued for exactly this kind of paradigm shift from within Islamic economics. Earlier work reconceived the waqf as an incorporated venture institution whose purpose is to make impactful, zero-waste halal enterprises successful and introduced equity-at-default as a compassionate contract that replaces collateral and foreclosure with partnership. Subsequent work engineered blended Islamic structures that mobilise social and commercial capital jointly for impactful small and medium enterprises pursuing the Sustainable

A Coordinate System of Competing Business Forms

The organising device of this paper is a Cartesian coordinate system that captures, in a single visual grammar, four competing business forms across two directional tensions (Figure 1). The horizontal axis measures the treatment of Nature, running from value extraction and the depletion of natural systems on the left toward their restoration and regeneration on the right. The vertical axis measures the treatment of Society, running from self-serving conduct and low or negative social impact at the bottom toward the uplifting of human well-being at the top. Read this way, the rightward and upward movements are not static labels but strategic transition vectors: the right captures movement from extractive or weakly restorative activity toward circular and regenerative relations with ecological systems, and the upper region captures movement from narrow profit maximisation toward stronger social value, governance, and stakeholder obligation.

Two features of the figure deserve emphasis before the quadrants are examined individually. The first is that the axes are non-substitutable. A gain on the Nature axis does not license a loss on the Society axis, and vice versa; the plane refuses the compensatory logic by which strong performance in one domain is allowed to offset weakness in another. The diagram’s value lies precisely in keeping the two tensions visible at once so that a firm cannot purchase ecological credit with social

The Linear, Open-loop Firm (Q3)

The lower-left quadrant represents the linear, open-loop firm in its purest form: business-as-usual extraction, profit-centred and value-depleting. Here economic value remains detached from ecological regeneration and only weakly connected to social welfare. The firm’s posture corresponds closely to the European Commission’s (2023) critique of the take-make-use-dispose model and to the OECD’s (2019) characterisation of the traditional linear system of extraction, ownership, and disposal. Its performance depends on throughput and ownership transfer; profit is realised at the point of sale, and end-of-life responsibility is externalised onto customers, communities, and ecosystems. The defining traits of this archetype are the prioritisation of short-term profit over people and planet, high extraction and pollution intensity, and weak or frankly exploitative treatment of labour and community. In coordinate terms, it sits at the negative pole of both axes—depleting Nature while doing little for Society—and it is the historical default from which every other archetype represents an attempted departure. Crucially, the linear firm is not irrational; within a price system that does not charge for waste, durability, or social harm, linearity is locally optimal. That observation matters because it implies that moving a firm out of Q3 will require changing the incentives it faces, not merely exhorting it to behave better.

easily misread. It is the linear-ESG firm: values-shifted but still nature-negative, mission-led yet resource-intensive. This is an important intermediate form because it demonstrates that a firm can improve its governance, ratings, disclosure, and stakeholder language without fundamentally redesigning its products, supply chains, or ownership logic. Such firms adopt sustainability reports, climate disclosures, and board-level oversight; they cultivate social purpose, ethical engagement, and governance excellence; and they may, thereby, satisfy genuine investor and regulatory demands. IFRS S1 and S2 materially strengthen the discipline of governance, strategy, risk management, and target-setting that these firms can credibly demonstrate (IFRS Foundation, 2023a, 2023b).

Yet the quadrant remains open-loop because none of this necessarily alters the material metabolism of the business. A

The Circular, Closed-Loop Firm (Q4)

The lower-right quadrant is operationally transformative in a way the left-hand quadrants are not. The circular, closed-loop firm redesigns products and asset flows around circular logic: it is nature-positive, but, as the figure warns, it can be technically circular yet socially blind. The circular-economy literature describes the relevant mechanisms in complementary terms. Bocken et al. (2016) distinguishes slowing, closing, and narrowing resource loops; Geissdoerfer et al. (2020) extends this with intensifying and dematerialising loops; and the OECD (2019) identifies circular supply, resource recovery, product life extension, sharing models, and product-service systems as the headline circular business models. The Q4 firm puts these into practice: it redesigns supply chains, extends product life through eco-efficient design, recovers value at end of use, and depollutes and restores natural systems where it can.

What this archetype does not guarantee is a comprehensive social logic. The figure is careful to label Q4 as nature-positive but society-negative, with low social inclusion or inequitable distribution as its characteristic shortfall, and the empirical literature supplies the corresponding caution: the OECD (2019) explicitly warns that circular models, though broadly favourable on life-cycle environmental grounds, can generate rebound effects and unintended consequences if they are not assessed systemically. A firm can close its material loops and still concentrate the resulting gains, displace labour, or deepen inequality. Circularity is thus a necessary advance over linearity, but it is

figure calls the Era of R—refuse, rethink, reduce, reuse, repair, refurbish, remanufacture, repurpose, recycle, and recover— whose cumulative effect is to restore rather than deplete natural systems. The regeneration of Society is carried by maqasid al-Shari’a, which orients the firm toward the protection of life, intellect, lineage, wealth, religion and toward long-term social prosperity and inclusion rather than narrow shareholder return; read together with the Sustainable Development Goals and the pillars of sustainable human development, with which the maqasid substantially converge. The regeneration of the Economy is the most distinctive and the most easily missed: it requires that the financial and contractual layer be redesigned so that value capture rewards durability, maintenance, and recovery rather than throughput so that the economy becomes a self-renewing system rather than a self-consuming one.

It is in this third regeneration that Islamic contract design does its decisive work, and it is the reason the regenerative quadrant cannot be reached by environmental engineering alone. This is the sense in which Islamic economics and finance can serve as an embedded framework for regenerative development rather than as an external overlay on a linear economy: the contractual layer is where regeneration is either secured or lost. Earlier work renders the financial markers of that regeneration concrete, extending the circular economy’s zero-waste and zero-emissions targets with two distinctively financial zeros—zero-interest and zero-foreclosures—so that the economy ceases to extract rent and ceases to liquidate enterprises in distress.

business-model design must move together if firms are to slow and close their loops. The implication for finance is direct and is taken up next: products meant to support circular transformation must themselves be designed around asset longevity, maintainability, recoverability, and traceability, or financing will remain misaligned with the very transition it claims to serve.

Form Follows Finance: Products as Governance Technologies

The transition from the left-hand quadrants to Q1 turns on a claim that is easy to state and consequential to accept: contract form is behavioural architecture. Islamic financial products are not neutral funding vessels whose only function is to move capital; they are governance technologies that shape conduct. A debt-like instrument that rewards volume tends to entrench throughput and short-term disposal, pulling even a well-intentioned firm back toward Q3. An ownership, leasing, or impact-linked structure, by contrast, can create standing incentives for maintenance, longer asset life, take-back, and better stakeholder treatment. This is why the same firm can behave linearly or regeneratively depending on how it is financed and why financing design is not downstream of business transformation but part of it.

Islamic finance offers a striking illustration of the same dynamic in reverse. A whole family of contracts that were originally

the one that governs the linear-ESG quadrant. IFRS S1 and S2 focus on the sustainability- and climate-related risks and opportunities that are reasonably expected to affect enterprise prospects; the Global Reporting Initiative (2021a, 2021b) instead centres the firm’s significant impacts on the economy, environment, and people; and EFRAG’s (2024) double-materiality framework explicitly combines impact materiality and financial materiality and ties both to the value chain.

For a regenerative business form, the double view is decisive. A repair network, a reverse-logistics system, or a waqf-funded water project may matter because it protects communities or ecosystems well before its effect crystallises as a short-term enterprise financial metric. In Islamic finance, this wider lens is not an imported novelty; it is consonant with maqasid and with the IFSB’s (2020) emphasis on social solidarity and inclusion. Materiality, properly understood, is therefore the bridge between the disclosure machinery of ESG and the regenerative ambition of Q1.

Designing Islamic Financial Products for the Regenerative Quadrant

From the design imperative, five Islamic financial product families emerge as especially well-suited to financing the move into Q1. Each is presented not as an instrument already dominant in the market but as a design archetype derived from the capabilities and barriers documented in the reviewed literature. Each

bonds: a public framework aligned to use of proceeds, project evaluation and selection, management of proceeds, and reporting, supported by second-party opinions and post-issuance tracking. The market already recognises circular-economy categories as eligible use-of-proceeds areas, alongside eco-efficient products and production technologies, pollution prevention, renewable energy, water, and biodiversity. A circular sukuk could therefore fund repair hubs, remanufacturing ecosystems, industrial-symbiosis parks, reverse-logistics systems, secondary-material platforms, sustainable buildings, clean transport, or waste-to-value infrastructure. The WB-IsDB (2025) report documents growing issuance and continued oversubscription in the green-sukuk market while noting the need for more diversified pipelines and more innovative structures—precisely the room into which a circular sukuk is designed to move.

social-fund tranche underwrites the cost of funds, and the public sector facilitates so that the impactful enterprise receives subsidised or effectively interest-free financing while each party’s motive is satisfied. Islamic social funds—zakat, waqf, and sadaqa—can be layered as first-loss, subordinate, or guarantee (kafala) capital that de-risks commercial money, which is precisely the blended-finance architecture, in Shari’a-compliant form, that the WB-IsDB (2025) report now calls for.

The Waqf-Supported, Zakat-Enabled MSME Transition Facility

The regenerative quadrant cannot be reached by large firms alone; micro, small, and medium enterprises must transition too, and they are typically the businesses most likely to fall between commercial-bank requirements and public-funding gaps. The IFSB (2020) notes that waqf, sadaqa, and qard can be integrated with Islamic financial products to serve inclusion objectives, and the WB-IsDB (2025) report shows that in Indonesia and Malaysia, zakat and waqf already help halal-industry SMEs obtain certification and adopt sustainable practices, even as a lack of financial resources and low ESG technical capability remain major barriers. A Circular-Maqasid-ESG facility for MSMEs could therefore use a layered structure in which waqf or philanthropic first-loss capital de-risks a commercial financing pool, while qard or concessional tranches fund audits, product redesign, cleaner equipment, water efficiency, repair tooling, or transition certification. Existing cash-waqf models for

the cost of circular operating models. One of the hidden barriers to repair, refurbishment, modular design, and reused-equipment systems is perceived performance uncertainty. Takaful can underwrite asset uptime, remanufactured-component performance, repair liability, or maintenance-contract fulfilment, and its underwriting criteria can be set to reward durability, traceability, training, occupational safety, and low-emission operation. So designed, takaful ceases to be a protective overlay and becomes an incentive mechanism for the regenerative quadrant—a way of pricing the reliability of circular systems so that they can compete with linear ones.

A Worked Application: Financing Geothermal Heat Pumping

Geothermal—or, more precisely, ground-source—heat pumping offers a near-ideal test of the framework because its difficulty is financial before it is technical. A ground-source system moves heat between a building and the stable temperature of the earth a few metres down, delivering both heating and cooling at a coefficient of performance several times that of combustion or electrical resistance, and the buried ground loop can last fifty years or more. At district scale, the University of Toronto’s King’s College Circle geoexchange—Canada’s largest urban ground-source system, comprising 372 boreholes drilled 250 metres deep and completed in 2024—provides heating and cooling to more than thirty campus buildings while avoiding roughly 15,000 tonnes of carbon dioxide equivalent each year. At the

regeneration of Nature through eco-efficient operation, not through narrowing material loops, and it should be described as such. And the rebound warning holds: cheaper comfort can induce additional consumption, so efficiency gains must be assessed at the level of the whole system rather than the single building.

Mapped against the five product families, geothermal assigns itself with unusual clarity. The servitised ijara facility is its natural primary structure. Because the ground loop is a long-lived asset whose entire value is its durability, a financier can retain ownership and charge for delivered heating and cooling—comfort as a service—rather than selling equipment outright. The building avoids the upfront drilling cost, while the financier, as owner, has every incentive to design for the fifty-year life, maintain the field, and recover residual value. An istisna’ contract can sit ahead of the ijara to fund the custom drilling and installation, with the financier commissioning the borehole field

move that lifts geothermal out of premium-villa Q4 into community Q1. Circular takaful then underwrites the residual technical uncertainty that unsettles both lenders and owners: borehole-field performance, heat-pump uptime, and the long-term ground-temperature drift that can erode efficiency in heavily cooling-dominated fields when a loop is undersized or thermally unbalanced. By pricing that risk— and by rewarding the thermal-response testing and proper sizing that prevents it—takaful lets a fifty-year asset compete on level terms with a five-year air conditioner.

The case is strongest in the GCC, where the framework’s host context and the technology’s advantage coincide. Air conditioning consumes on the order of seventy per cent of electricity in Saudi Arabia, and air-source units perform worst exactly when demand peaks, in air approaching 50°C, whereas the stable, cooler ground offers a far better heat sink. Peer-reviewed simulation for Riyadh finds ground-source systems delivering a higher coefficient of performance than air-source equivalents—about 4.1 against 3.8—with roughly a third lower annual energy use, against an eleven-year payback. That payback profile is itself the argument for patient, risk-sharing, socially subsidised Islamic capital rather than short-tenor commercial debt. Read through the coordinate system, geothermal heat pumping regenerates all three domains at once: Nature, through avoided combustion; the Economy, through an asset stewarded across half a century rather than churned; and Society—but only if the financing is deliberately designed to carry the technology

covers the inclusion of SMEs, affordability, job quality, worker safety, access to clean water and energy, and broader community benefit. Governance assurance covers Shari’a review, use-of-proceeds controls, impact assurance, and external second-party opinion or audit. These four layers correspond, not coincidentally, to the three regenerations defined earlier—of Economy, Nature, and Society— and held together by an assurance layer that keeps the other three honest.

Governance carries a particular burden here. The evidence that stronger Shari’a governance improves social and governance performance in Islamic banks without yet consistently improving environmental outcomes (is significant because it implies that governance quality alone is not enough: environmental performance depends on whether governance is actually attached to operational and contractual redesign. In practice, Shari’a boards, compliance functions, and internal Shari’a-audit processes should widen their attention from the permissibility of transaction form to the substance of transition design, treating durability, fair risk allocation, transparency of use of proceeds, and measurable public benefit as governance questions rather than peripheral sustainability topics. AAOIFI’s (2025) expanding governance architecture provides an institutional basis for that move.

Rebound effects mean that the savings from circular models can trigger additional consumption elsewhere, partially offsetting environmental gains. Measurement instability means that ESG ratings remain noisy and that divergence can distort incentives or license selective disclosure. Standard fragmentation means that the absence of common taxonomies and uneven capacity across jurisdictions continues to impede Islamic climate finance.

Moreover, substantive dilution means that a product can be labelled green, social, or Shari’a-compliant without demonstrably moving a firm toward durability, reparability, recovery, inclusion, or regeneration. These hazards do not invalidate the framework; they establish that governance and measurement are constitutive elements of the regenerative model rather than optional accessories. The argument carries its own limitations honestly. It is conceptual and design-oriented rather than empirical, and so it does not test the financial performance or risk characteristics of the proposed product families.

It draws on a literature that is stronger for sustainable sukuk and climate finance than for some other circular categories, particularly maintenance-linked Islamic finance and circular takaful. Because Islamic-finance jurisdictions differ in legal enforcement, tax treatment, governance centralisation, and disclosure maturity, the proposals here should be treated as adaptable archetypes rather than one-size-fits-all blueprints. Conceptual design work is nonetheless valuable at this stage because the literature itself repeatedly identifies the need for

it, belongs instead to the family of offsets: it ring-fences capital to eligible uses and accounts for benefit, compensating in one place for activity elsewhere. Substitutions and offsets are indispensable—they change incentives and direct capital—but neither, on its own, alters the underlying metabolism of the firm, which is precisely why a Shari’a-compliant, sukuk-funded, ESG-disclosing enterprise can still sit in the linear-ESG plateau of Q2.

The decisive category is transformation, and the paper has shown it at two depths. At the level of the asset, geothermal heat pumping is a genuine transformation: it replaces combustion with heat-moving, changing the production metabolism rather than the contract that finances it. But the largest transformation is of the business model itself—the relocation of the firm out of linear extraction (Q3), disclosure-led linear-ESG (Q2), and socially blind circularity (Q4) into the Circular- Maqasid-ESG form of Q1. This is the transformation that all the substitutions and offsets are ultimately in service of; absent it, they refine a linear enterprise without regenerating it. That ordering follows directly from the non-substitutability of the two axes. Because a gain on Nature cannot be traded for a loss on Society, and because mizan forbids transgression of the balance, offsets and substitutions cannot stand in for structural change: no amount of compensatory accounting or contractual reform can carry a firm across the quadrants while its business model remains linear. The central thesis is, therefore, both simple and demanding. The future of Islamic sustainable finance lies not in substituting and offsetting one’s way to a slightly greener linearity but in
